Kartongit

Kartongit is a term used in packaging design to describe a conceptual class of cardboard-based packaging materials intended to combine protective performance with sustainability. It covers reinforced and multi-layer constructions that use recycled fibers and optional barrier coatings to improve moisture resistance and printability.

Composition and variants: Core materials are typically kraft or testliner papers sourced from post-consumer or post-industrial fibers. Variants may include single-wall, double-wall, or triple-wall constructions, as well as laminates where cardboard cores are bonded with thin polymer or starch-based layers. Surface finishes can include water-based coatings, inks for branding, and thin barrier films to enhance shelf life.

Production and processing: Standard kartongit production follows conventional carton-board manufacturing: pulping, refining, forming into sheet stock, and converting into boxes or display pieces. Multi-layer constructions often involve adhesive bonding and selective lamination, with processes designed to preserve recyclability while achieving desired stiffness and rigidity.

Properties and performance: Key metrics include tensile strength, bending stiffness, edge crush resistance, and impact protection. Moisture management and barrier performance vary by coating and layering, influencing suitability for different contents and climates. Dimensional stability and printability are important for logistics and marketing.

Environmental aspects: Recyclability and end-of-life handling are central considerations, with a preference for separable layers and recyclable coatings. Life cycle analyses typically weigh energy use, water impact, and waste generation, aiming to minimize environmental footprint while maintaining performance.

Applications and market: Conceptual kartongit materials are explored for consumer electronics, cosmetics, food, and e-commerce packaging, where lightweight, strong, and recyclable packaging is valued. See also: corrugated fiberboard, paper recycling, biodegradable coatings.
